Programs and Capability |
|
*1 The measurement range and accuracy of reflectorless, and time required to measure may vary by the shape, size of surface area and reflection rate of the target and its environment. The measurement range of reflectorless is determined by the white side of the Kodak Gray Card. (Kodak is a trademark of Eastman Kodak Company)
*2 Reflector sheet: PENTAX genuine Reflector sheet
*3 The measurement range may vary by conditions of the environment. Normal conditions: 20 km visibility with slight shimmer Good conditions: 40 km visibility, overcast, no heat, no shimmer and moderate wind.
*4 EDM measuring time is determined in good conditions. It may take longer than usual to measure the distance exceeding 4000 m in prism mode. Also, the measurement time in reflectorless mode is influenced by the share, size and surface area and reflection rate of the target and its environment.
*5 Quick mode, which functions with prism and reflector sheet, is effective only under normal mode (1 mm) and up to 500 m.
*6 Distance measurement has been done every 30 second for the Operation time for “ETH+EDM”
